Fishing is made of many things.  Some detail, some luck, some skill.  It varies from light to dark, from river to river, from season to season.  In Autumn the leaves are crisp and crackle under foot.  It is the time of trout and water and all that goes with it.  The rivers cool as the sunlight dissipates, shortening the days and, thru falling rains, dampening the grass.  The grasses are laced with dew drops as the fresh morning moves on
